While FluView is an invaluable tool, it does have some limitations:
Reporting delays: There can be a lag between when data is collected and when it is reported, which may affect the timeliness of the information. Underreporting: Not all cases of flu are reported, particularly milder cases that do not require medical attention. Geographic variability: The quality and completeness of data may vary by region, affecting the accuracy of the overall picture. Evolving virus: Influenza viruses constantly evolve, which can complicate efforts to track and respond to flu activity accurately.
